FLASH memory, also known as FLASH memory, is a memory with the characteristics of multiple erasing and rewriting. At present, FLASH memories are widely used. For example, FLASH memory can store configuration programs for FPGA chips in a hardware platform.
At present, a FLASH memory is directly welded on each hardware platform or a circuit board of a certain circuit, and when an FPGA chip on the hardware platform needs to be configured, a program stored in the FLASH memory can be burned through a program JTAG download port. XCF32P from XILINX is a widely used FLASH memory, and XCF32P is also a high performance 32Mbit FLASH memory.
